When is a dedicated spotter required when working near power lines?

A dedicated spotter is required when a crane can reach within 20 feet of power lines due to the increased risk of electrocution and other serious hazards associated with working near overhead power lines. This distance is established based on safety regulations and guidelines to ensure that operations remain safe and that the crew is adequately prepared to handle any potential hazards arising from proximity to electrical lines.

The presence of a spotter helps to maintain safe distance protocols, assists the operator in navigating the area safely, and ensures that everyone understands the risks involved. The spotter can communicate directly with the crane operator to prevent accidental contact with power lines, which could lead to life-threatening situations.

The other distances mentioned would not meet the specific safety standards recognized in the industry for ensuring appropriate oversight and communication when working around electrical hazards. It is crucial for safety protocols to comply with established guidelines to minimize the risk of accidents.
